SAFETY-SHUTTER FOR BOTTLlNG-MACHINES.

SPECIFICATION forming part of Letters Patent No. 454,980, dated June 30,1891.

Application filed July 21, 1890- To all whom it may concern:

Be it known that we, EDWIN S. HUGHES and HIRAM HUGHES, of GlenwoodSprings, Colorado, have invented an Improvement in Safety-Shutters forBottling-Machines, of which the following is a specification.

This invention relates to improvements in safety-shutters for bottlingmachines, whereby an accidental bursting of the bottle prevents thethrowing of glass and injury to the operator. e

The objects of our invention are to provide a cheap andsi mple attachment of the above class to be applied to ordinary bottling-machines andto be automatically operated or closed at each descent of thecorking-head and automatically returned to an open position at eachelevation thereof.

Other objects and advantages of the invention will appear in thefollowing description, and the novel features thereof will beparticularly pointed out in the claims.

Referring to the drawings, Figure 1 is a perspective of a portion of abottling-machine provided with our improvements. Fig. 2 is a detail, inside elevation and enlarged, of one of the shutters and its supports andconnecting devices. Fig. 3 is a detail of the connecting device orhinge, the same being shown in perspective. Fig. 4 is a transverse'section through the same. Fig. 5 is a transverse sec tion similar tothat of Fig. 4, but illustrating a slightly-modified construction.

Like numerals of reference indicate like parts in all the figures of thedrawings.

1 designates the table or base of an ordinary bottling-machine, throughwhich pass the opposite reciprocating rods 2, and from the table betweenand adjacent to the rods 2 are fixed cylindrical rods 3. The rods 2 areconnected at their lower ends by a cross-yoke 4, located under thetable, to which is hinged, as at 5, a treadle 6, designed to be operatedby the foot of the operator, and when so depressed to be afterwardreturned automatically by a pair of coiled springs 7, connected to theyoke a and to the under side of the table 1.

8 designates the usual cross-head, through the center of which is formedan eye 9, in which operates the reciprocating corkinghead 10. Thecross-head is provided at its ends with eyes 11 and 12, the inner eyeshe- Serial No. 359,468. (No model.)

ing fixed to the rods 3, and the outer eyes serving as guides for therods 2.

Upon each of the rods 3 is mounted 2. cylinder or sleeve 13, the samebeing adapted for easy rotation and being maintained against verticalmovement by means of limiting-collars 14:, secured in position throughthe medium of set-screws 15, passed through the collars and impingingupon the rods 3. Each of the cylinders or sleeves 13 is provided with aspiral slot 16, the same being vertical for portions of their lengthoccurring near the upper and lower ends thereof. In each of the slotsprojects a stud 17, formed upon the inner side of its collar 18, one ofthe latter being mounted upon each of the rods 2 and secured in anadjusted position by means of a pair of set screws 19.

To each of the cylinders or sleeves 13 there is secured by means ofsecuring-plates 20 projecting therefrom a shutter 21, the same beingprovided at about their centers with semicircular concavities 22, sothat they combine to embrace a cylindrical object, such as a bottle;

In operation, the bottle being placed in position after filling andpreparatory to the final corking, the foot of the operator is employedto depress the treadle 6, which brings down the corking-head to theposition necessary to drive the cork. As the treadle is depressed theyoke 4 necessarily follows against the tension of its springs 7 and inits descent draws the rod 2 downwardly. The studs of the collars 18 ofthe rods beingin engagement with the spiral slots 16 of the sleeves orcyl inders 13 and said collars descending with the rods 2 necessarilycauses a partial rotation of each of the sleeves, and with them theshutters, which are thus swung to a position to embrace the body of thebottle. It will be observed that by'reason of the fact that the slots 16are made straight at their upper and lower ends the stud will travel forsome distance before and after the actuation of the sleeves, so thattime is given for the corkinghead to wholly descend into contact withthe cork of the bottle after the shutters have been swung to anembracing position, and during the movements of the studs in thestraight portions of the slots the cylinders or sleeves and the shuttersremain uninfluenced. As

soon as the corking has been completed and H the treadle 6 released frompressure the springs 7 return the parts to their normal positions, andin their ascent the studs 17 swing the sleeves and shutters around tothe first position, and thus the shutters release the bottle.

As shown in Fig. 5, I may provide the cylinders with a spiral rib 23 andsubstitute for the single stud 17 a pair of studs 24, each provided withan anti-friction roller adapted to rise upon the sides of the studs.

From the above construction it will be apparent that we provide a cheap,simple, durable, automatically-operated, and effective safety-shutterapplicable to the ordinary bottling-machines of the present day.

Having described our invention,what we claim is 1. In abottling-machine, the combination, with the table, the oppositereciprocating rods, the spring for returning the same, and the treadleconnected to and adapted to depress the rods, of the stationary rodslocated adjacent to the reciprocating rods, the loose sleeves mountedupon the latter and provided with spiral ways, collars mount-ed upon thereciprocating rods and provided with projections engaging said Ways, andsafety-shutters connected to each of the sleeves,substantially asspecified.

2. The combination, with the table, the reciprocating rods, the springfor returning the same, and the collars mounted on the rods and providedwith studs, of the fixed rods, the cylinders or sleeves mounted thereonand provided with spiral grooves, each receiving a stud of said collars,and safety-shutters projecting from the sleeves or cylinders,substantially as specified.

3. The combination,with the table 1, the reciprocating rods 2,the yokeconnecting the rods, the treadle 6, pivoted to the yoke, the coiledsprings 7, connecting the yoke and table and serving to retract theformer, and the collars 18, having studs 17 and set-screws 19 foradjusting the same, of the cross-head 8, having the eye 9,the plunger10, and the eyes 11 and 12, the sleeves 13, the fixed rods 3, upon whichthe sleeves are loosely mounted, said sleeves being provided with spiralslots 16, the collars 1i, mounted on the rods 3 and provided withset-screws 15,and the safety-shutters 21, connected to the sleeves andhaving the concavities 22, substantially as specified.
